I am looking for a 7.1 receiver and I am really a sony guy. I like the STR-DN1020 but I have also been looking at some of the ES models as well. I know there is no point in getting a higher end receiver if I don't have a high-end tv, speakers, blu-ray player etc., but since the receiver is the heart of the setup, I don't want to sell myself short if I might be missing out on some features. I have a decent tv, an older sony 52" lcd and I plan on getting some higher end sony speakers. Should I shell out the money for let's say the new STR-DA3700ES or another model ES, or just stick with one of the lower end ones like the DN1020 or even the DH820? I own several blu-rays and a lot of dvds which I suppose would benefit from the ES's upscaling capabilities, but I'm not sure what to do. I appreciate and feedback.
